I see. I'll have to remain neutral on this one as this command isn't necessary, but it wouldn't hurt to add. I suggest that if you have a player /ignore'd they shouldn't be able to send a /weba message to you, as it could be used to spam someone. This concept is similar to how you can't message another player who has /ignore'd you. Being able to toggle this on and off would also fix the problem of being spammed with welcome back messages.
I honestly think this is a cool idea. To prevent spam, maybe it should show the message only to the one player?
Not much use for this. But this can kind of promote spam if anyone do /weba and the chat is filled with "Welcome back..."
It is i explained that. its not in global chat, it sends a message to the player Im going to edit this i will make it so you can only do it to one player every 30 seconds
Not needed at all. When someone comes back honestly I only see a couple people welcoming them back. No support
